It is proposed to use a sorbent based on polyurethane foam and natural raw material chitosan for water purification from oil pollution. Traditionally, chitosan and materials with its use are mainly used as purifiers of water and other media from heavy metal ions. This paper provides information on the use of chitosan, which is preliminary isolated from the waste from processing f various beetles, dead bees, etc. Sorbent synthesis occurs by mixing the components of polyurethane foam and chitosan in a very short time, which allows you to produce and use it directly on site.
